Abstract Energy alternatives have been one of the most important research focal areas of the last decade due to the
imminent lack of fossil fuels. This motivation has allowed the evolution of the materials science field in
areas such as electrochemistry, where high availability, low cost and negligible environmental impact are
the desired principal qualities. For this reason, as an example of a photoelectrochemical device, we have
proposed the use of natural dyes from 37 agro-industrial wastes in dye-sensitized solar cells. We obtained
dyes from red cabbage, radish and roselle wastes with a good stability for eight hours with a constant… More >
